Title: Catch mechanism; drawer interlock
Inventor: ATKINS DAVID SEAGROVE
IPC: E05B65/465
Filed: 1992-09-21
Abstract: A catch and a locking system for a cabinet with a plurality of drawers (10) which includes a number of catch mechanisms (25) each of which is associated with a respective drawer. Each catch mechanism has a retaining member (28), a biasing member (30) and a spring (48) which acts on the biasing member.

Title: Colorimeter measuring light transmission in a liquid
Inventor: DADACHANJI FALI MINOCHER
IPC: G01N21/59
Filed: 1994-06-29
Abstract: A colorimeter, for assessing the colour of an indicator, includes a housing having a guide passage 12 for a transparent liquid sample container 22, and a light source 14 and light sensor 16 mounted in the housing so that light from the source 14 can reach the sensor 16 after traversing the passage 12. A light transmitting reference body 10 is mounted for passage through the housing. Processing means receives signals from the sensor 16 and calculates a value significant of the transmission loss of light. Displacement of the sample container 22 into the passage 12 causes the container and the body 10 to pass in succession between the light source 12 and the sensor 16, and the processing means calculates, on the basis of a comparison between the sensor signal when the body 10 is interposed between the light source and the sensor, and the signal when the container 22 is so interposed, the percentage transmission loss for the liquid. <IMAGE>

Patent GB-2285363-A (GB)
Title: Vehicle internal noise reduction system
Inventor: TAMAMURA MANPEI
IPC: H03H21/00
Filed: 1994-12-23
Abstract: The system reduces noise by producing a cancelling sound from a speaker 14 based on a tap value formed and updated in an adaptive filter 7. The tap value of the adaptive filter is formed by convoluting a filter coefficient having a similar band pass characteristic to the frequency characteristic of the speaker 14 into the tap value formed by the adaptive control of the adaptive filter for the purpose of operating the noise reduction system stably without causing distortion or divergence in the system. This ensures that deficiencies in the speaker do no cause instability. <IMAGE>

Title: Method of fabricating optical fiber doped with rare earth element using volatile complex
Inventor: LEE YONG-WOO
IPC: G02B6/00
Filed: 1995-10-06
Abstract: A method is disclosed of fabricating an optical fiber doped with a rare earth component using a volatile complex, which flattens the light frequency response under a stimulated emission of radiation principle using a modified chemical vapor deposition method. Silicon tetrachloride (SiCl 4 ) and oxygen are injected into a quartz reaction tube under a heating process, so that a cladding layer is repeatedly deposited. Then, a volatile organic metal chelate, silicon tetrachloride and oxygen are injected into the quartz reaction tube, and heated and water-cooled to form a porous layer. At the same time, a rare earth element is deposited on the porous layer, to thereby form a core layer. Thereafter, via a high heating process, a preform is completed. Then, an optical fiber is obtained from the preform via a drawing-out process. Here, hydroxide ions (OH* box - middle top *) which occur as the organic ligand is volatilized and cause an optical loss of the optical fiber and removed as the porous layer is formed by the water-cooling, and an added rare earth content is easily controlled, so that the rare earth with high concentration is evenly distributed. Also, since the core layer adopts SiO 2 and Al 2 O 3 as a host material instead of GeO 2 , the difference in a refractive index between the cladding and core layers becomes greater then 0.015, to thereby provide the optical fiber with excellent optical characteristics.
